WELL-TUBE.

SPECIFICATION forming part of Letters Patent No. 311,024, dated January 20, 1885.

.Application filed October 2, 1884. (No model.)

To all whom it may concern.:

Be it known that I, FREDERICK W. MILLER, a citizen of the United States, residing at Brooklyn, in the county of' Kings and State of New York, have invented new and usef'iil Improvements in Well-Tubes, of' which the following is a specification.

This invention relates to certain improvements in well-tnbes, as pointed out in the following specification and claims, and ill astrated in the accompanying drawings, in which- Figure l represents a longitudinal central section. Fig. 2 is a transverse section in the plane a x, Fig. l.

Similar letters indicate correspondi ng parts.

In the drawings, the leiter A designates the strainer of the well-tube, which consists of the wire-gauze b and tube B. The tube is provided with a series of holes, c, which are countersunk, and the wire gauze extends round the tube B. The holes a are countersunk, so that the water from the outside has access to the interior of` the tube B through a larger number of holes or meshes of the wire gauze than it would have if' t-he outside diameter of the holes a were the same as their inside diameter. This will be readily understood by referring to Fig. 2, where the inside diameter of one of the holes a is indicated by the lines an., Of course the same object could be attained by boring holes into the tube B, the diameters of which would be equal to the outside diameters of' the holes a; but by doling so the tube B would be greatly weakened,

By making the holes a countersunk the object of' obtaining a sufficient supply ot' water is attained without reducing the strength ot the tube B beyond the desired limit.

C is the suction-pipe, which is secured to the upper section ofthe well-tube Bby means of two flanges, c d, the liange c being secured upon the well-tube and the iange d upon the suction-pipe, leaving between them an open space, e, through which the external atmosphere communicates with the interior of the well-tube. The pump connects with the suc tion-pipe by means of' elbows D, or by any other suitable coupling. By these means a :firm connection is effected between the pump, the suctionpipe, and the well-tube, and at the same time the air has free access to the well tube B, so that no vacuum can form therein.

The well-tube B extends beneath the strainer A, so as to' form a chamber, f, in which the fine sand which passes through the strainer accumulates, so that it is not liable to be sucked up by the pump. The chamber f is closed at the bottom by a plug, g, and the suction-pipe extends down into the chamber, which is filled with water up to the level of the strainer. By this arrangement the mouth of the suction-pipe is a considerable distance below the level of the water in the well-tube B, and the pump is not liable to suck air if the water in the well gets low.

I am aware that a strainer for a well-tube has been made composed ofa stock with countersunl; holes, and of' a lining of wirefgauze situated in the interior of said stock. In this case the countersunk holes do not increase the effective area of? the strainer, and they are only countersunk in order to produce sharp edges for the purpose of facilitating the operation oI" soldering the wirevgauze lining to the inner surface of the stock.

What I claim as new, and desire to secure by Letters Patent, is

l. The combination, with the suction-pipe O, of a strainer, A, composed of the well-tube B, the countersunk holes in said tube, and the wire-gauze jacket secured to the outer surface ofthe well-tube. substantially as and for the purpose described.

2. The combination, substantially as hereinbefore described, with the suotion-pipe C andthe well-tube B, of two flanges, c d, one being secured to the suction -pipe and the other to the well-tube, the open space e formed between said flanges and communicating with the interior of the well-tube, and the coupling for connecting the pump to the suction-pipe.
